The principal objects of the invention are to provide a small easilyportable form of hand loom which may be readily taken apart or assembledso that it may be carried in a small light package whereby hand weavingmay be widely practised.

Further and important objects are to provide a loom which may be veryeasily operated and in which the heddle rods may be positivelymanipulated to permit a wide range of pattern control.

The principal features of the invention consist in a rotatable weaving`frame whereby the warp may be easily, quickly and accurately wound,heddle supporting blocks secured to the frame, heddle rod liftsvertically slidable in the blocks, and means for raising the heddle rodsupports, holding them in varying positions and lowering themsimultaneously.

In the accompanying drawings, Figure 1 is a perspective View of myimproved loom.

Figure 2 is an enlarged perspective detail of a portion of one of theside bars of the frame and one of the adjustable heddle rod supports.

Figure 3 is an enlarged Vertical section through the heddle rod supportshowing one of the individual heddle rod lifts in elevation.

Figure 4 is a horizontal sectional view of the heddle rod support takenon the line 4-4 of Fig ure 3.

Figure 5 is an enlarged side elevational view of the frame.

Figure 6 is a perspective detail of one of the heddle rod supportsshowing portions of the heddle rods in raised and lowered positions.

Referring to the accompanying drawings, the stand for supporting theloom frame is formed of a base I with two rigid uprights 2 between whichis supported a cross rod 3, preferably of round metal which is securedin place by a wing nut 4 threaded on one end.

A pair of bars 5 preferably of wood. and square in cross section arepivotally mounted to swing on the rod 3. These bars are formed withthreaded extensions 6 and 1 at opposite ends.

Broad flat end bars 8 and 9 are slidably mounted on the threadedextensions of the side bars, the bar 8 being clamped against theshouldered end of the side bars by nuts Il) and the bar 9 being securedin adjusted positions on the threaded extensions 1 by nuts I I arrangedeither side thereof. The distance between the end bars 8 and 9 may thusbe readily adjusted.

The bars B and 9 are rounded on their outer faces to receive the warpthreads I2 which are wound around the frame and when the winding iscompleted by simply rotating the frame on the rod 3 the end bars may bereadily adjusted to tighten the warps to the desired tension.

A comb I3 is temporarily clamped between the end bar 8 and the shouldersI4 on the side bars to assist in the winding. This comb is provided witha removable top bar I5 which is temporarily held in place by pins I6inserted through said bar and the comb frame.

After the warp threads are wound on the frame the comb may be releasedby loosening the nuts on the extensions 6 of the side bar thus releasingthe comb for use in the weaving operations when desired.

The side bars 5 of the frame are formed with longitudinal grooves II anda plurality of spaced holes I8 extend through the bars from the bottomof th grooves.

Heddle support blocks I9, preferably of wood are formed with tongues 20in the bottom end to t into the grooves I1 and threaded rods 2| securedin said blocks extend through the holes I8 and are secured in place bythumb nuts 22 on each side bar of the frame.

The blocks I9 are formed with a plurality of transverse vertical slots23 and a narrow vertical slot 24 bisects the posts between the slots 23.

A metal heddle rod lift 25 is slida'bly mounted in each of the slots andis formed with thin vertical fins 26 which slide in the slot 24, thusholding the holders 25 from displacement, while per- -mitting them toslide freely in the vertical slots l23.

The lifts 25 are each formed with a hooked projection 21 extending wellout from the outwardV side of the blocks I9 to enable their being of theslot the spring plate snaps in beneath the projection thus holding thelift in its elevated position. These spring plates extend completelyacross the outer side of the blocks I9 and will engage and hold any oneor all of the holders I5 in a raised position. A handle 30 secured toeach The lifts 25 are formed with notches 3I- on the inward sides at thetop into which the notched ends 32 of the heddle rods 33 extend, saidrods being thus held from falling out if the loom is allowed to swing.

'I'he heddle rods 33 are formed of flat wood strips and carry the loopedheddle cords 34 which are looped around certain of the warp threads. f

The weaverwill select the various warpsl that he may desire to havelooped to each heddle rod and While the present illustration shows foursuch rods, it will be readily understood that holders may be provided toaccommodate any desired number of rods.

It will be noted that a small rubber or leather buiTer 35 is placed atthe bottom of each' of the vertical slots in the blocks I9 to cushionthe dropV of the heddle holders and thus prevent undesirable noise inthe operation of the loom.

It will be readily understood by those skilled in the art of weavingthat a loom such as described will be extremely easy to manipulate andthat very accurate and rapid work may be accomplished by the heddlearrangement provided and by the means provided for the easy and accurateWinding and adjusting of the warps.

It will also be appreciated that the Several members may be very easilyand quickly taken apart or Vput together when it may be desired totransport the loom and when disassembled the parts may be groupedtogether in a small light package which will be Very easy to handle andthe parts are all of simple, strong and durable construction.

What I claim as my invention'is:

1. In a loom the combination with a rectangular frame having adjustableend bars and a stand pivotally supporting said frame, of blocks mountedon the sides of said frame each having a plurality. of vertical slotstherein, heddle rods, members slidable in each of said slots havingnotches to hold the ends of said heddle rods and having projections forlifting said slidable members, spring means for engaging and holdingVsaid slidable members in a raised position, and means for operatingsaid spring holding means to release all of said slidable memberssimultaneously.

2. A deviceas claimed inclaim 1 in which each of the slidable members isformed With a lug projecting from the slots in which they slide, a flatbowed spring plate secured to the outerside of each block adapted to beengaged by the projecting lugs of the slidable members, and ahandlevsecured to each spring plate adapted to be pressed outwardly tospring said plate to release all of the slidable members engaging saidplate simultaneously.
